FEM-Design API is mostly developed to give users access to most of the model data. We believe that users should not be constrained by our idea of engineering, but they should have the freedom to manipulate the data in a way that works best for them!
FEM-Design, the main software, has a really pleasant user interface that exports all the results with good logic.
However, the API will give you the freedom to nest/manipulate the data in any way you want and export it with a small script. In the picture above, I have shown how straightforward it is to save some data to a text file.
